Maryland authorities said a 28-year-old man taken into custody early Friday morning made threats to launch an attack at his workplace and identified himself as "a joker," according to national reports.

ABC 7 News in Washington reports the suspect Neil Prescott, 28, of Crofton, Md., was being dismissed from his job as a subcontractor at the supply company Pitney Bowes when he allegedly made several threats to shoot his boss while calling himself "a joker" in calls to a co-worker.

Police found more than 25 guns including assault rifles and thousands of rounds of ammunition while searching Prescott's home, according to the Baltimore Sun.

No charges have yet been filed. Prescott was transported to Anne Arundel Medical Center in Annapolis, Md., for an evaluation by doctors, reports Fox 45 in Baltimore.
